Used these on a 180mm quad at 3S with AfroESC 12A ultra light /w BEC. Used 4x4.5 Bullnose and GemFan 4045 ABS. I suppose I lucked out, no issues so far after 10-15 batteries. After a longer session, one motor becomes slightly warm but thats it. The CW/CCW threading is slightly confusing at first, but fine thereafter, and Ive used a Sharpie permanent marker to indicate the direction on the CW (grey) nuts to help. I use a 10mm socket to assist in removing the prop nuts / spinners when theyve tightened themselves too much after a prop break. The leads were easy to tin and solder. The included M2x6mm screws worked with my Diatone ET 180, although I filled them down slightly shorter for peace of mind as they we too close to the motor stator windows (you can see them just under the bell looking at the side profile). Remember to use a thread-locker, as the screws can loosen themselves quickly. Ive purchases backup motors, but have not as yet need them. They do seem slightly unbalanced, and certainly dont sound smooth, but for the novel size and nominal price are fine for my needs.

I was really hoping these would be good, sadly my experience has been poor with them.
The first set of 4 I purchased for a 155 frame. One of the motors did not spin true out of the box, it caused some vibration but I didn't want to spend the time to RMA so I used it anyway. This same motor would often not want to start but would spin up after a few tries. Less than one month later I had a fairly tame crash in grass and ended up bending the inner shaft and and prop shaft, very surprised that a impact with grass would do so much damage.
I ordered 2 replacement motors and had another crash the same day as I installed them, resulting in another bent shaft. Even after straightening the shaft the motor no longer runs as I believe the magnets have shifted.
Overall you get what you pay for, and the durability of these has left me looking for something else.

I bought six of these motors. One went up in smoke during takeoff on the first flight. The motor actually did spin up normally, then it stopped suddenly and sparks came out of the case. Now the windings are totally fried and another $10 are wasted!
I'm absolutely certain there was nothing wrong with my setup. I used the suggested multistar 10a esc v2, a 3s lipo and 4 inch props.
